KNOGKIDOWN BUILDING.

Application filed May 1?, 1924. Serial No. 713,946.

' To all wfiom it may concern:

Be it known that I, HENRY Rnennaunn, a citizen of Germany, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Knockdown Buildings, of which the following is a specification.

The present invention relates to buildings, and more particularly to a kllOCk-ClGWD building constructed of molded units of cementitious material.

An object of the present invention is to construct a building of cast units of cementitious material.

Another object is to make building units of a cementitious material, which units may be assembled into buildings of different sizes and shapes.

Another object is to make a building by assembling interlocking units of cementitious material.

I11 order to attain these objects, there is provided, in accordance with one feature of the invention, vertical columns having recesses therein in which wall panels may be inserted, and across the tops of which, interlocking beams are anchored by means of reinforcing rods extending above the tops of the vertical columns and penetrating the interlocking beams. Roof panels are laid transversely on top of longitudinal interlocking beams, and are heldin position by a reinforcing unit embedded in each roof panel, a portion of which reinforcing meu1- ber extends beyond the lower surface of the roof panel to engage a beam. A ridge cap for the roof composed of overlapping angular members, the end members of which may be ornamented as desired.

These and other features of the invention not specifically mentioned will be more fully brought out .in the following description and the accompanying drawings, 'wherein similar reference characters refer to the same parts throughout the various views.

Referring to the drawings:

Figure 9, shows a wall panel hm inga window incorporated therein; and

Figure 10, is a view in isometric projection-of a corner of a cement base with a column positioning socket imbedded therein.-

Referring to the drawings in detail:

A concrete base 1 is provided with sockets 2 at each point where the center of a column A is to rest. The sockets 2 may be formed by imbedding a portion of metal pipe in the cementitio'us material of which the base 1 is made while the material is still soft. Each column A has a reinforcing member a of metal rod which may extend the entire length thereof and which projects both at the top and at the bottom thereof to form an anchor. Sides of columns which are to hold panel sections are routed as at 5 to engage the ends of panels to be inserted therein. Sides of columns which are to have a door adjacent thereto are rabbeted as at 6, and on a side of an o pcning which is to support the door, pivot pins 7 are imbedded in the cementitious material of which the column is constructed, while it is in the process of being molded. Columns in opposite side walls of a structure are interlockingly connected in pairs by means of T-beams B which. interlockingly engage the columns by means of the anchor rods 4: which are inserted in holes 3 in the projection opposite ends of the horizontal portion of lit) the cross member of this beam, and extending upwardly in the form of a loop in the central upright portion thereof. T-beams are routed as at on each side of the central upright portion and on the upper side of the cross member to receive end panels 14 to be later described in detail. mediate each laterally adjacent pair of up right columns in the wall portions of a building, panels G are inserted, by sliding from the top downward. It is optional where window panels 26 are placed since these panels are of the same dimensions externally as a solid panel. The panels are of inverted ii-shape on top and bottom for the purpose of preventing rain from driving through a joint between vertically adjacent panels.

Resting one upon each end of the T- shaped cross members, are plates ll which may extend the entire length of a building ui'iless the building is too long to permit handling of a beam of such length. The ends of anchor members 4 extend entirely through and beyond T-members B and the ends of these anchor rods are inserted in holes 12 (see Figure 2) of the plates 11. The plates 11 interlock-ingly connect the wall units which make up a side of a buildmg.

Resting upon the top of each central upright portion of the T -beam, is a ridge-beam 13 of the shape shown in Figure 2, and this ridge beam has notches 3'? in the sides thereof to engage and support end panels 14: inserted therein. The ridge beam 13 is held securely in place, and interlockingly supports T-beams B, by means of anchor rods 15 (see Figure 6), which engage holes 16 in the ridge beam.

Triangular panels 1i slip into position from above and are interlockingly engaged by notches in plates 11, ridge beam 13, and the routings 10 in the sides of the upright portion and the top of the cross portion of the T-beams. Each triangular panel member 1-l has a notch located centrally of the upper edge of the panel, said notch having vertical sides and a horizontal bottom. Resting in these notches, and supported therein is a beam 16 which gives an added support toroof slabs carried thereon.

Roof slabs 17 may extend the entire length of the slope of the roof in a small building,

such as a garage, and constructed to over-- lap at the edges as illustrated at 18 in Fig-. ure 1. The upper tongue 19 of the overlapping portion has a straight outer side, and the under surface thereof is parallel with the top plane of the slab. In the lower tongue 20 of the overlapping joint, the outer side thereof is straight, but the top surface thereof slopes down inwardly from the edge to form a trough or gutter to carry down rain water. The inward and downward Intersloping of this surface also prevents capillary action in this joint, which would be present if the adjacent surfaces of the joint were contiguous throughout. The lower edge 21 of the panels may be scalloped or otherwise patterned as desired. Slabs for either end of a roof section are made with an overlap tongue on but one edge as illustrated, the other edge being finished square. The roof slabs are held in position by friction, and the weight of the material of which they are constructed, but an additional anchoring means is provided in a member 22 imbedded in the slab, the nose portion 23 of which extends beyond the surface of the slab, and may hook over the top edge of the supporting beam 16. A ridge covering is formed of successive slabs 24 of inverted V cross section and having overlapping joints between adjacent sections, of the same general nature as those between adjacent roof slabs. End ridge slabs may be decorated as shown at 25 if desired;

Upon the erection of a building made in accordance with the present invention, all

exposed joints may be given a light coat of cement to seal them. This cementing of the joints does not affect the demountable feature of the building, since' such a joint will not be of equal strength with the building units which it joins, and the units are easily separable at such joints.

-A window panel 26 is constructed of the same exterior shape as an ordinary wall panel. A molded retaining rim 33 forms a frame which extends inwardly from three sides of an opening 27 in the panel, and a bar 28 is suspended from a staple 29 imbedded in the cementitious material during the process of molding. The rod 28 is provided with a slot 31 which fits over a stud 32 imbedded in the body of the slab on the opposite side of the window from the staple 29. A locking pin 30 may be suspended from a chain secured to a staple'or other means also imbedded in the body of the slab during. the molding thereof. A window 39 is slidably inserted in the frame 33 and maybe locked in place by swinging the bar 28 across the top of the window, slipping the slot 31 over the stud 32 and inserting the locking pin 30 in a hole 34: in stud 32..

The building shown in Figure 1 is the only one of various types which may be constructed in accordance with the invention herein disclosed, others being immediately apparent to a mechanic or one skilled in the art. It is, therefore, not intended to limit the invention to the building illustrated, but to include all which come within the spirit and scope of the invention. Buildings made in accordance with the present invention may 'beset up and disassembled without the use of tools other than a trowel, which may be required if it is desired to cover the cracks with a light coat of cement after the building is erected.
